Method and device for monitoring an elevator support characterizing propery

摘要

An elevator support monitoring device in an elevator system and a method for monitoring an elevator support characterizing property, preferably an electrical resistance, of the elevator support or of a tension support of the elevator support for a sudden change in the characterizing property. A state of the elevator support is determined by evaluating several consecutive, sudden changes in the characterizing property.

主权项

1. A method of monitoring an elevator support comprising the steps of:
monitoring at least one characterizing property of the elevator support with an elevator support monitoring device connected with the elevator support; detecting an abrupt change in the at least one characterizing property with the elevator support monitoring device; and determining a state of the elevator support with the elevator support monitoring device by evaluation of a plurality of successive ones of the abrupt change in the characterizing property.
